生物活性

Suberoyl bis-hydroxamic acid (Suberohydroxamic acid; SBHA) is a competitive and cell-permeable HDAC1 and HDAC3 inhibitor with ID₅₀ values of 0.25 μM and 0.30 μM, respectively.Suberoyl bis-hydroxamic acid renders MM cells susceptible to apoptosis and facilitates the mitochondrial apoptotic pathways.Suberoyl bis-hydroxamic acid can be used for the study of medullary thyroid carcinoma (MTC).

体外研究

Suberoyl bis-hydroxamic acid (10, 20 or 50 μM; 24 hours) combination with TRAIL improves apoptosis extent, and when TRAIL is combined with 20 μM SBHA (itself causing only 10–15% apoptosis), resulting in 45–50% cell death.
Suberoyl bis-hydroxamic acid (20-50 μM; 10-20 hours) alone has little effect on the expression of the proteins Bcl-xL, Mcl-1, and has albeit mildeffect on Bax. When it combines with TRAIL,which increases the ratio of relative protein expression of Bcl-xL and Bax in early periods, while the change in the ratio of Mcl-1 and Bax increases later in MM-BI and Ist-Mes2 cells.
Suberoyl bis-hydroxamic acid (30 μM; 6 hours) causes accumulation of acetylated histone H4 in MEL cells.

Apoptosis Analysis

Cell Line:	MM-BI and Ist-Mes2 cells
Concentration:	10 μM, 20 μM or 50 μM
Incubation Time:	24 hours
Result:	Showed a cooperative effect in cell apoptosis.

体内研究

Suberoyl bis-hydroxamic acid (intraperitoneal injection; 200 mg/kg; every 2 days; 12 days) reveals a marked increase in the active form of Notch1 (NICD) with a concomitant decrease in ASCL1. It reduces the MTC tumor growth.

Animal Model:	Nude mice injected with human MTC cells
Dosage:	200 mg/kg
Administration:	Intraperitoneal injection; every 2 days; 12 days
Result:	Resulted in an average 55% inhibition of tumor growth in SBHA treatment group.
